Quad throttle body setup

Check it out. If they can extract another 60+kw from a 1.5 12 valve SOHC Excel, i think we can do better. If anyone is interested in developing such a system with EITHER the CA20E or the KA24E, let me know.  ;D

I've got 5mm oversized throttle bodies on my 3.5 magna.  I got them from RPW in perth, and the difference was pretty special.  The quad set ups are fairly pricey, and you'd want to have done exhaust, filters, etc. before even thinking about this sort of thing.

i been thinking about it, i seen it done twice, once on an mx5 and the 2nd time on a toyota echo.

in both cars, the quad throttle setup alone increased power by 60%

however, i figured that its a little pricey for me at the moment, and it will do away with all my schmicko cold air setup. i have other things to to first, but i might do it later down the track.

can it be done to the ca20?
i'd be interested down the track as well.....60% increase in power is huge......135kW 2L would be schweet!

2.0L 4 -------> 3.0L 6. Does this mean a 4.0L 8 next?? or back to a 2.0L......turbo!

i figure with the mods i alrady have planned in the future, fitting a quad throttle setup would have no problems at taking my baby to 180kw... and thats if the quad throttle setup only provides me a 50% power increase. but then, it might not give me that much either.

GLi_Timmy: Yes, it can be done quite easily, however best results are tuning with an aftermarket ECU.

I would like to develop such a system for various Nissans, however mainly for the CA20E and the KA24E. 91nismotrx, if you want just email me and i'll discuss with you how it would be best run.

Instead of one large throttle body for 4 cylinders, you have a smaller (around 45-50mm in diameter) throttle body for each cylinder. Each cylinder then gets lots more air, but you then need to increase the fuel going in.

There are always stupid questions like:

Why did I go to the pub at lunch time and drink four pots and then come back to work and try to not get caught using the internet while I'm pretending to work?

Why after drinking beer at lunch, do I suddenly have a suden urge to sleep this afternoon?

Why am I so hungry all of a sudden?


The ramblings of an alcoholic in the making. :P

I still dont think they are stupid questions.
But if you do, why did you ask them in the first place?
Why would anyone ask a stupid question for? To get a stupid response?

Ok then.have it your way.
Anyone with half a brain, who knows a little about cars, would know what a quad throttle body is. But i never said that in the first place. I was trying to be positive and support your answer. I did that on the second occasion too. Both times, you had to be stupid in your reply.
So, your question isnt really stupid. Youre just a dumbarse.

And what makes you even dumber is, if you had bothered to read the first post, you would use the link to read up on Quad throttle bodies, that are produced by RPW in WA.

Well Mitza I know a couple of people who know a little bit about cars and they did not know what a quad throttle body is.
And I know some fellas who ,know a bit about cars who do know what a quad throttle body is.
It is just one part of the picture if someone does not know about it, it does not make them stupid.

GLi Timmy I imagine was saying it sounds stupid in the context that it may sound stupid to someone in the forum who takes it for granted because he knows what the term means already.

Really we are all amatuers in the car world unless you can supply proof that you have done extensive work to a car by yourself. Post up a mechanics certificate or documented proof with photos etc. What does it really matter, if someone does not know something then you just tell them.

Ryan... Would you have to get rid of your CAI setup? On the pics on that link with the hyundai setup they still have a pipe going out from the carbon fibre box. Could you not hook your pipe up to the box instead of that black one.
That is assuming the setup would be pretty much the same as on the hyundai.
Why they used a hyundai as a test vehicle... YUK!!

thank you sssgtr for answering my question and explaining what a quad throttle body is. ;D
for mitza, i have nothing to say to you, read awesome_trx's post over and over, understand it,  memorise it, know it backwards, then maybe u will get somewhere! :)

You have a PhD from my post do ya Mitza... Hmmm...
In order for that to be true you would have to attain a certain amount of credit points about say 360! and write a painfull and long thesis...
Since I would not wish upon anybody I will suffice to say this.

Mitza I hope that if you optain a PhD from me you will get somewhere.
I will give you a PhD if you just simply "Get along"....

Timmy I did not write my post to shoot anybody down or for anyone to use what I wrote to shoot someone down.
I am simply saying that it was a bit of miscommunication.

Just move on and don't worry about what has happened.

Now both of you  :-* and make up..  :D

If you insist on continuing it then send eachother an email or explore your feelings and connect with one another through ICQ, MSN etc...

yes good point awesome_trx. I too, am sick of this continued bitching on here!
But, i wasnt implying that your post was shooting anyone down. I was simply saying that what u said was completely right, and if mitza read it then he would see that there really is nothing to argue about.  :)

yeah, if i go ahead with the quad throttle setup then i'd have to get rid of my cai, in which case i'd offer it for sale on these forums. i wouldnt go back to an air box though, i think it would defeat the purpose. i'd go for the 4 individual air filters.

as for them using a hyuandai as a test car.. i dunno.. they're cheap, there are millions of them on the road & they showed that really, quad throttles can be applied to any car. from when i skimmed thru the link, it said it increased the power of the hyundai from 60-something kw to 110 or so kw. which would have to impress anyone i think.

i reccon using the hyundai as a test model is a good idea, shows what can be done to a sh!tter of a car.. so from there u would think its all uphill for any other car ;)

Ryan,

Hooking up four air filters would mean you would need four air flow meters I think, this would be a bit expensive wouldn't it?

Depending on the price I would just be happy to use the carbon fibre box they can provide.

If you used their carbon fibre box you could still use your cold air setup.
Those power increase figures were using the carbon fibre box from what I can see. Still pretty good.

If you're all so keen for info on oversized/quad throttle bodies, speak to David at www.rpw.com.au or at www.fastmagna.20m.com in the Mitsubishi performance forums.  Although RPW mainly do Mitsu, Hyundai performance, David is a very helpful guy and will most likely be willing to answer a few questions and maybe put you in the right direction of someone who can do some stuff for your Pintara.

Instead of using 4 individual air filters, a fibreglass/carbon fibre plenum can be fabricated as is done on RPW's hyundai, connected to the plenum would be large ducting to say a skyline/300zx MAF sensor, then perhaps 2 of K&N's larger filters; however it would be much better to utilize a programmable ECU to get maximum gains from the quad setup.
Individual air filters would require a MAP sensor to determine how much air is going in based on pressure measurements, however i am not sure whether 4 MAP sensors would have to be utilized. Then aftermarket programmable ECU's would have to be run.

Thanxs dude I saw the info on the site about the carbon fibre chamber.. and the nice pics

That is what I was sayin to Ryan earlier.

Four filters would be more hastle I think.

The cool thing is that you could possibly still s.c the quad set up which would be really original and give even more power.

ok i am interested in this mod of quad throttle bodies. who can i talk to about this. just one thing though, i have already got exhaust and extractors modified, but do i need an aftermarket ecu, or can i use the one i have with the powerchip i have on it. will this still work for the time being? send me an email [email protected] and we can start to discuss business on this conversion. i have round $2,500 so let me know if it is possible. cheers. oh yeah and i have a 89 ti with a ka24e.
